背棘 (总数) : 5 - 8; 背的软条 (总数) : 12 - 17; 臀棘: 3 - 4; 臀鳍软条: 9 - 10; 脊椎骨: 57 - 61. Distinguished from Thymallus arcticus by the following unique characters: maxillary usually reaching anterior margin of eye; pelvic fin grey, lacking red stripes; body without red spots; dorsal fin greyish, with parallel rows of round dark spots; gill rakers 19-30, averaging about 24-26 (Ref. 59043). Caudal fin with 19 to 21 rays (Ref. 2196).
尾鳍有 19 到 21个鳍条。 (参考文献 2196)
Inhabits submontane reaches of rivers with a hard sand or stone bottom and well oxygenated, cold and fast-flowing water (Ref. 59043). Prefers running, well-oxygenated waters of rivers (Ref. 30578). In Scandinavia, it occurs in clear lakes and freshened part of northern Baltic basin. Usually lives in hollows behind boulders and shaded water under overhanging vegetation (Ref. 59043). Gregarious, forms schools (Ref. 2196). Feeds mainly on insects (Ref. 9696), nymphs, small worms and crustaceans (Ref. 30578). Breeds in shallow stretches, usually 20-40 cm deep, or riffles, with moderate current of about 0.5 m/s and clean gravel bottom (Ref. 59043). Can be captured with natural bait (insect larvae) or with artificial fly. Very sensitive to pollution (Ref. 30578).
群居的, 形成鱼群.(参考文献 2196) 偏爱河的流动且溶氧度高水域。 (参考文献 30578) 栖息于河的清澈上游，底部为砂或碎石的地方; 也出现于湖中, 极少在半淡咸水 (波罗的海). 主要吃昆虫 (参考文献 9696) ，蛹，小的蠕虫与甲壳动物。 (参考文献 30578) 能被用自然诱饵 (昆虫幼生) 捕获或者使用人工鱼饵。 非常敏感对污染.(参考文献 30578)
